All of these deadly weapons exist, and have existed for many decades beginning in 1960s. How do they know they work? They test them. Back in 1970s, in defense industry, we tested them from tops of buildings located several miles away from each other. I think we know where they tested recently, and evidence is overwhelming.

Funny thing, a comic book that is all true. I've not been able to debunk much, if any of it.
I still have a copy tucked away. Back then, we all knew who Rockefellers were. Might want to rethink Rocky & Bulwinkle cartoons.

Bottom electric version can be modernized using either light bulbs or a thermal heating wire like a tungsten wire from a toaster oven, in fact, could use thermostat too if you can find an old 2nd hand one to gut, and a small fan, planned vent placements. Could also use an ancient all metal on/off hot plate and a big Rheostat to control the temps, like we used to use in old metal fridges we gutted to use for good sized home meat smoker. YUM!
